Description

Technical Field

[0001] This utility model relates to the field of edible fungi cultivation technology, and more specifically, to a stirring device for edible fungi culture media. Background Technology

[0002] Edible fungi refer to large, edible mushrooms (macrofungi), commonly known as mushrooms. There are more than 350 known edible fungi in China, most of which belong to the Basidiomycota. Edible fungi are large fungi that can be consumed by humans. Specifically, edible fungi are mushrooms that can be eaten. Mushrooms are a class of large fungi that can form large, fleshy (or gelatinous) fruiting bodies or sclerotia that can be eaten or used for medicinal purposes. Edible fungi occupy an important position in the food industry, and the quality of the culture medium is crucial in their cultivation process.

[0003] However, existing edible mushroom substrate mixing devices have the following problems during use:

[0004] In traditional edible mushroom substrate mixing operations, manual mixing is the primary method. Manual mixing is not only labor-intensive and time-consuming, but also extremely inefficient, and it's difficult to ensure uniform mixing. Unevenly mixed substrate has inconsistent moisture and composition distribution, which adversely affects the growth environment of edible mushrooms, hindering their healthy growth and severely restricting the yield and quality improvement of edible mushrooms. This is detrimental to the cultivation of edible mushrooms and the large-scale development of the edible mushroom industry.

[0005] This invention can efficiently stir edible fungi culture media, precisely control humidity, ensure stable quality of culture media, guarantee smooth production process, and improve production efficiency. Summary of the Invention

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a stirring device for edible fungi culture media.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stirring device for edible fungi culture medium, comprising: a base, a feeding box fixedly installed on the top of the base, a water tank fixedly installed on one side of the feeding box, a stirring box fixedly installed on the upper end of the base, a cover plate connected to the upper end of the stirring box by bolts, the feeding box and the water tank being fixedly installed on the upper right side of the cover plate, with the water tank located on the left side of the feeding box, an inclined plate fixedly installed inside the feeding box, a protective box fixedly installed on the front of the feeding box, a motor fixedly installed inside the protective box, a crushing roller fixedly connected to the rear of the motor, the crushing roller being located below the inclined plate, a water inlet opening at the upper end of the water tank, an alarm fixedly installed on the rear side of the upper end of the water tank, and several nozzles fixedly installed at the bottom of the water tank.

[0008] A further preferred embodiment: A power box is fixedly installed on the left side of the mixing tank, and screws are rotatably installed on both the front and rear sides inside the mixing tank. One end of the screw passes through the mixing tank and is rotatably connected to the power box. A spiral blade is fixedly installed on the surface of the screw. A discharge port is opened on the left side of the bottom of the mixing tank, and the interior of the mixing tank is inclined to the lower left.

[0009] A further preferred embodiment: a main gear is fixedly connected to the output end of the motor, a secondary gear meshes with the right side of the main gear, both the main gear and the secondary gear are rotatably connected to the front of the feed box, and a connecting rod is fixedly connected to the rear end of both the main gear and the secondary gear.

[0010] A further preferred embodiment: the connecting rod is rotatably connected to the feed box, the rear end of the connecting rod passes through the feed box and is fixedly connected to the crushing roller, and the crushing roller is rotatably connected to the feed box.

[0011] A further preferred embodiment: the water tank has sliding grooves at both the front and rear ends, a movable plate is slidably connected in the sliding grooves, and a pressing rod is fixedly installed on the front and rear sides of the bottom of the movable plate.

[0012] A further preferred embodiment: buttons are fixedly installed on both the front and rear sides of the bottom inside the water tank. The buttons are waterproof and located below the pressing rod. Beneficial effects

[0013] 1. The system is equipped with a motor, main gear, auxiliary gear, and crushing roller. The motor serves as the power source, and its output end is connected to the main gear. After starting, the main gear rotates stably. The main gear meshes with the auxiliary gear to transmit power, driving the auxiliary gear to rotate synchronously. This gear transmission method ensures the stability and efficiency of power transmission and reduces power loss. The connecting rods connected to the rear ends of the main and auxiliary gears transmit the rotation to the crushing roller, enabling the crushing roller to rotate stably in the feed box. During the culture medium processing, the rotating crushing roller can break larger culture medium blocks that slide down from the inclined plate into smaller particles. In this way, the culture medium has a more uniform particle size before entering the mixing tank, which is conducive to thorough mixing with water during subsequent mixing, improving the mixing effect and quality, and thus providing a higher quality culture medium for edible fungi cultivation.

[0014] 2. Equipped with a movable plate, a pressing rod, a button, and an alarm, the movable plate slides in a groove inside the water tank, moving up and down with changes in water level. The pressing rod at its bottom also moves accordingly, cooperating with a waterproof button at the bottom of the water tank. When the water level drops to a certain level, the movable plate moves the pressing rod down, pressing the button triggers the circuit or control system, causing the alarm to sound and reminding the operator to replenish water in time. This design achieves automatic monitoring and alarm functions for the water level in the tank, avoiding insufficient humidification of the culture medium due to low water levels, which would affect the mixing effect. At the same time, it ensures the continuity and stability of the mixing operation, reduces the workload of frequent manual checks of the water level, improves the intelligence level of the entire device, and provides a reliable water supply guarantee for the mixing of edible fungi culture medium.

[0015] 3. By incorporating a mixing tank, screw, and spiral blades, the mixing tank, serving as the core space for material mixing, features a unique downward-sloping structure that encourages the culture medium to naturally gather to one side. This lays the foundation for efficient mixing by the screw and spiral blades. Driven by the power unit, the screw rotates stably, and the spiral blades fixed to its surface rotate synchronously. As the spiral blades rotate, their special structure powerfully propels the culture medium within the mixing tank, enabling both circular motion (responding to material displacement at different locations) and axial motion (promoting material distribution along the screw's axis). Combined with the inclined structure of the mixing tank, the culture medium continuously tumbles and moves left and right during mixing, ensuring thorough mixing with moisture from all angles. This not only significantly improves mixing efficiency and ensures uniform moisture and composition of the culture medium, creating an excellent environment for edible fungi growth, but also effectively reduces mixing time, lowers energy consumption, and enhances overall production efficiency.

[0016] 4. In summary, this edible mushroom substrate mixing device, with its structure including a mixing tank, spiral blades, crushing rollers, nozzles, and an alarm, achieves comprehensive mixing of the substrate through the inclined structure of the mixing tank, screw, and spiral blades. This significantly improves mixing efficiency and uniformity. The crushing rollers break up large pieces of substrate during the feeding stage, making the particle size more suitable for subsequent mixing and optimizing the mixing effect. The nozzles precisely spray water from the tank onto the substrate in a mist form, ensuring humidity control. The alarm, linked to the moving plate, pressing rod, and buttons inside the tank, monitors the water level in real time. An alarm is triggered immediately if the water level is too low, preventing water shortage from affecting humidification and mixing, and ensuring the continuity and stability of the production process. These components work together to comprehensively improve the quality of substrate mixing, reduce energy consumption, and increase production efficiency. Attached Figure Description

[0022] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0023] Please see Figure 1-4In this embodiment of the utility model, a stirring device for edible fungi culture medium includes: a base 1, a feeding box 2 fixedly installed on the top of the base 1, a water tank 3 fixedly installed on one side of the feeding box 2, a stirring box 101 fixedly installed on the upper end of the base 1, a cover plate 102 connected to the upper end of the stirring box 101 by bolts, the feeding box 2 and the water tank 3 are both fixedly installed on the upper right side of the cover plate 102, and the water tank 3 is located on the left side of the feeding box 2, an inclined plate 201 is fixedly installed inside the feeding box 2, a protective box 202 is fixedly installed on the front of the feeding box 2, a motor 203 is fixedly installed inside the protective box 202, a crushing roller 207 is fixedly connected to the rear of the motor 203, the crushing roller 207 is located below the inclined plate 201, and a water inlet 301 is opened at the upper end of the water tank 3. An alarm 302 is fixedly installed on the rear side. Several nozzles 307 are fixedly installed on the bottom of the water tank 3. A power box 103 is fixedly installed on the left side of the mixing box 101. Screws 104 are rotatably installed on both the front and rear sides inside the mixing box 101. One end of the screw 104 passes through the mixing box 101 and is rotatably connected to the power box 103. Spiral blades 105 are fixedly installed on the surface of the screw 104. A discharge port 106 is opened on the bottom left side of the mixing box 101. The interior of the mixing box 101 is tilted to the lower left. Edible fungus culture material is put into the feeding box 2 through the top opening. At the same time, an appropriate amount of water is injected into the water tank 3 through the water inlet 301 at the top of the water tank 3 to prepare for adding water during the subsequent mixing process. The motor 203 inside the protective box 202 is turned on. When the power switch is turned on, motor 203 starts running, driving the crushing roller 207 fixedly connected to it to rotate. Due to the presence of inclined plate 201, the culture medium slides down along inclined plate 201 under the action of gravity, gradually approaching and contacting the rotating crushing roller 207. The crushing roller 207 crushes the culture medium, breaking larger pieces into smaller particles, which facilitates more uniform mixing in the subsequent process. The crushed culture medium falls from the bottom opening of the feed box 2 directly into the mixing box 101 below. Because the mixing box 101 is inclined to the lower left, the culture medium will naturally gather on the left side of the mixing box 101. After the culture medium enters the mixing box 101, several nozzles 307 at the bottom of the water tank 3 are turned on. The water in water tank 3 is sprayed evenly onto the culture medium in mixing tank 101 in the form of a mist, so that the culture medium obtains an appropriate amount of moisture. During this process, if the water level in water tank 3 drops to a certain level, the alarm 302 on the upper rear side of water tank 3 will sound an alarm to remind the operator to replenish the water in time. Then, the power device (such as motor and transmission mechanism) in power box 103 is turned on. The power is connected to the screws 104 on the front and rear sides inside mixing tank 101, which drives the screws 104 to rotate. As the screws 104 rotate, the spiral blades 105 fixed on the surface of the screws 104 also rotate. The rotation of the spiral blades 105 will push the culture medium to make circular and axial movements inside mixing tank 101. Due to the inclined structure inside mixing tank 101,As the culture medium is propelled by the spiral blades 105, it continuously tumbles and moves left and right within the mixing tank 101, ensuring thorough mixing with water and achieving uniform stirring. Once the culture medium is uniformly stirred, the discharge port 106 on the bottom left side of the mixing tank 101 is opened. Due to the downward and leftward tilt of the mixing tank 101, the stirred culture medium is smoothly discharged from the discharge port 106 under gravity for subsequent edible mushroom cultivation. After discharging, the power unit in the power box 103, the nozzle 307 at the bottom of the water tank 3, and the motor 203 in the protective box 202 are shut down, stopping the equipment operation. The mixing tank 101, the feeding box 2, and other components are cleaned to remove any residual culture medium, keeping the equipment clean and ready for the next use.

[0024] In this embodiment of the utility model, a main gear 204 is fixedly connected to the output end of the motor 203, and a secondary gear 205 meshes with the right side of the main gear 204. Both the main gear 204 and the secondary gear 205 are rotatably connected to the front of the feed box 2. A connecting rod 206 is fixedly connected to the rear end of both the main gear 204 and the secondary gear 205. The connecting rod 206 is rotatably connected to the feed box 2, and the rear end of the connecting rod 206 passes through the feed box 2 and is fixedly connected to the crushing roller 207. The crushing roller 207 is rotatably connected to the feed box 2. When the motor 203 inside the protective box 202 is opened, the output end of the motor 203 starts to rotate. Since the main gear 204 is fixedly connected to the output end of the motor 203, the main gear 204 will rotate synchronously with the output end of the motor 203. The secondary gear 205 meshes with the right side of the main gear 204. During the rotation of the main gear 204, the secondary gear 205 is driven to rotate through the meshing transmission between the gears. Both main gear 204 and auxiliary gear 205 are rotatably connected to the front of the feed box 2, ensuring the stability of gear rotation. The rear ends of both main gear 204 and auxiliary gear 205 are fixedly connected to connecting rods 206, and connecting rods 206 are rotatably connected to the feed box 2. In this way, the rotation of the gears can be transmitted through connecting rods 206. The rear end of connecting rod 206 passes through the feed box 2 and is fixedly connected to crushing roller 207. As connecting rod 206 rotates, crushing roller 207 also begins to rotate. Because crushing roller 207 is rotatably connected to the feed box 2, crushing roller 207 can rotate stably inside the feed box 2. When the culture material in the feed box 2 slides down the inclined plate 201 under the action of gravity to the vicinity of crushing roller 207, the rotating crushing roller 207 can crush the culture material, breaking larger culture material blocks into smaller particles, preparing for the subsequent culture material to enter the mixing tank 101 for mixing.

[0025] In this embodiment of the invention, the water tank 3 has sliding grooves 303 at both the front and rear ends. A movable plate 304 is slidably connected within the sliding grooves 303. A pressing rod 305 is fixedly installed on the front and rear sides of the bottom of the movable plate 304. A button 306 is fixedly installed on the front and rear sides of the bottom of the water tank 3. The button 306 is a waterproof button and is located below the pressing rod 305. When the water level in the water tank 3 changes, the water will exert a buoyant force on the movable plate 304. As the water level in the water tank 3 rises, the buoyant force on the movable plate 304 increases, and the movable plate 304 will slide upward within the sliding grooves 303. Conversely, when the water level in the water tank 3 drops, the buoyant force decreases, and the movable plate 304 will slide downward within the sliding grooves 303 under its own weight. The pressing rod 305 fixedly installed on the front and rear sides of the bottom of the movable plate 304 will move with the up and down movement of the movable plate 304. Button 306 (waterproof button) is located below the pressing rod 305. When the water level in the water tank 3 drops to a certain level, the moving plate 304 slides down to a certain position, and the pressing rod 305 contacts and presses the button 306 below. After the button 306 is pressed, it will trigger the corresponding circuit or control system, which will cause the alarm 302 fixedly installed on the rear side of the upper end of the water tank 3 to sound an alarm, reminding the operator that the water level in the water tank 3 is too low and needs to be replenished in time. When water is added to the water tank 3, the water level rises, the moving plate 304 slides upward under the action of buoyancy, the pressing rod 305 disengages from the button 306, and the alarm 302 stops sounding. Through this structural design, the movement of the moving plate 304 and the pressing rod 305 is driven by the change in water level to realize the monitoring and alarm function of the water level in the water tank 3, ensuring that there is enough water in the water tank 3 to humidify the culture medium during the stirring process.

[0026] Working principle: Open the top opening of the feeding box 2 and slowly pour the edible fungus culture medium to be stirred into the feeding box 2. The culture medium will fall onto the inclined plate 201. Pay attention to controlling the feeding speed and amount to avoid excessive accumulation of culture medium, which will affect the subsequent crushing effect. Inject an appropriate amount of water into the water tank 3 through the water inlet 301 at the top of the water tank 3. The water level should be maintained within a suitable range to prepare for adjusting the humidity of the culture medium during the subsequent stirring process. Connect the power supply and turn on the power switch of the motor 203 inside the protective box 202. The motor 203 starts to run. The main gear 204, which is fixedly connected to the output end of the motor 203, rotates synchronously with the output end of the motor. The auxiliary gear 205 meshes on the right side of the main gear 204. During the rotation of the main gear 204, the transmission is achieved through the meshing of the gears. The main gear 204 and the auxiliary gear 205 are both rotatably connected to the front of the feed box 2, ensuring the stability of the gear rotation. A connecting rod 206 is fixedly connected to the rear end of both the main gear 204 and the auxiliary gear 205, and the connecting rod 206 is rotatably connected to the feed box 2. As the gears rotate, the power of the gears is transmitted through the connecting rod 206. The rear end of the connecting rod 206 passes through the feed box 2 and is fixedly connected to the crushing roller 207. The rotation of the connecting rod 206 drives the crushing roller 207 to start rotating. Because the crushing roller 207 is rotatably connected to the feed box 2, it can rotate stably within the feed box 2. Due to the presence of the inclined plate 201, the culture material in the feed box 2 slides downwards along the inclined plate 201 under the action of gravity, gradually... As the feed material approaches and comes into contact with the rotating crushing roller 207, the rotating crushing roller 207 crushes the feed material, breaking larger pieces into smaller particles to facilitate more uniform mixing later. The crushed feed material falls from the bottom opening of the feed box 2 directly into the mixing box 101 below. Because the mixing box 101 is tilted to the lower left, the feed material naturally gathers on the left side of the mixing box 101. After the feed material enters the mixing box 101, the control switches of several nozzles 307 at the bottom of the water tank 3 are turned on. The nozzles 307 spray water from the water tank 3 evenly onto the feed material in the mixing box 101 in the form of a spray, so that the feed material receives an appropriate amount of moisture. The power unit in the power box 103 is then turned on. (Such as motors and transmission mechanisms), the power is connected to the screws 104 on the front and rear sides inside the mixing tank 101, driving the screws 104 to rotate. As the screws 104 rotate, the spiral blades 105 fixed on the surface of the screws 104 also rotate. The rotation of the spiral blades 105 will push the culture medium to make circular and axial movements inside the mixing tank 101. Due to the inclined structure inside the mixing tank 101, the culture medium will also continuously roll up and down and move left and right inside the mixing tank 101 during the process of being pushed by the spiral blades 105, so that the culture medium and water are fully mixed and uniformly stirred. The stirring time is reasonably controlled according to the properties of the culture medium and the stirring requirements. Generally, it is necessary to continuously stir for a period of time to ensure that the moisture and composition of the culture medium are evenly distributed.As the water level in water tank 3 changes, the water exerts buoyancy on the movable plate 304. When the water level in water tank 3 rises, the buoyancy on the movable plate 304 increases, and the movable plate 304 slides upward in the slide groove 303. When the water level in water tank 3 drops, the buoyancy decreases, and the movable plate 304 slides downward in the slide groove 303 under its own weight. The pressing rods 305, which are fixedly installed on the front and rear sides of the bottom of the movable plate 304, move with the up and down movement of the movable plate 304. When the water level in water tank 3 drops to a certain level and the movable plate 304 slides downward to a certain position, the pressing rods 305 will contact and press the waterproof button 306 below. After the button 306 is pressed, it triggers the corresponding circuit or control system, causing the alarm 30, which is fixedly installed on the rear side of the upper end of water tank 3, to activate. 2. An alarm is triggered to remind the operator that the water level in water tank 3 is too low and needs to be replenished promptly. Upon hearing the alarm, the operator replenishes water into water tank 3 through inlet 301. As the water level rises, the moving plate 304 slides upward under buoyancy, disengaging the pressing rod 305 from the button 306, and the alarm 302 stops sounding. After the culture medium is evenly mixed, the control switch of the nozzle 307 at the bottom of water tank 3 is turned off to stop water spraying. Then, the valve of the outlet 106 on the bottom left side of the mixing tank 101 is opened. Because the mixing tank 101 is tilted downwards to the left, the mixed culture medium is smoothly discharged from the outlet 106 under gravity. A suitable container can be used to collect the culture medium below the outlet for subsequent edible fungus cultivation.
